Siebel Marketing 8.1.1.3: Unsubscribes

Hello all,

Currently, we are using the vanilla one click unsubscribes in which when a contact clicks on the unsubscribe url in the email, it directly unsubscribes the user thru CTD daemon to Siebel. But we want to change the unsubscribtion process to two steps in which:

1. User clicks on the unsubscribe link in the email

2. User lands on to Page 1 with unsubscribe button

3. User clicks on the Unsubscribe button and lands on to Page 2, user has to unsubscribe only after landing in to this page.

Please advise how would I be able to achieve this with multiple pages involved in the unsubscribtion process.
